Recent studies by an international team of physicists could have possibly discovered the first signs of dark matter. Dark matter accounts for roughly 90% of the universe, particles that are hypothesized about, but not yet observed. The hypotheses are inferred from the rotational speed of galaxies, which are spinning faster than just gravitational forces can account for. The particles that the researchers found showed as "two tiny pulses of heat" which were found over the course of two years in pieces of geranium and silicon that had been cooled nearly to absolute zero. Although they say there is still a 20% chance that the pulses came from background radioactivity from the surrounding area, the results were "tantalizing, but not definitive".
